Hive vs Logic 30+

[wheelq]

Hi,

I have checked all posts on this forum, and I could not find anyone in the same situation as me.

Hive model: Dual Channel
Hive Wiring: Never changed, just kept switching boilers
Why dual: Long time ago this was the only model available. I do not use and I'm not planning to use water preheating.
Problem: With the new boiler I have no idea how to wire the hive to it

Hive wiring (always worked, never changed):




Previous boiler wiring (worked perfectly fine with hive wiring posted above):



New boiler ideal Logic 30+ combi (Room Stat/Timer is attached but not not connected on the other end):



I am not an electrician, so instructions over hints would be very useful

That's single channel Hive wiring, because:

1) There is a link between terminals L and 1. The dual channel Hive has the link to live made internally

2) terminal 4 is the heating control with dual channel, and terminal 3 the single channel, and your wire is in 3.

Anyway, if you say it has been working like that, then it is a single channel. The Hive N & L supply remains. Remove the link between L and 1 and the two black wires from the "boiler room stat / timer" go in terminals 1 & 3, it doesn't matter whicy way around.

But really, using green / yellow (earth) wires for live wires is not good.

The single channel was out for many years before the Dual channel

Out of interest, how do you know?

I’m not sure why you Line, Neutral and possibly switch live are installed using circuit protective conductor? Very bad practice.

Ok, so this is dual channel, but someone wired as if it was one (maybe it was the boiler I had before those two). Let me rewire as instructed for dual and will let you know.

Hive dual channel doesnt use links, and heating on is terminal 4 on hive dual channel

post a pic of your hive receiver unit, if you actually have a dual channel that wiring wouldnt work

ok so single channel has 1 (common) and 3 (heating on)
since I have a dual channel, there is no common, so what should be the wiring for dual?

Something is wrong here. You post a photo of a backplate wired up as a Single Channel Hive and tell us:

Hive wiring (always worked, never changed):

Then you post a photo of a Dual Channel Hive receiver, which would never have worked on the backplate with the wiring connected as you show. I refer you to the diagram from the Hive manual in my earlier post. The 'Heating On' wire of the Hive Dual Channel is connected to terminal 4. and you don't have a wire in terminal 4!

So I believe that either there is something you are not telling us, or if not, this is a wind up.

If it is a Dual Channel Hive, the N & L are straightforward. And then the switched live terminal from the boiler (that has one of the black wires in) goes to Hive terminal 4. They are the only 3 wires needed. No links required. The other room stat terminal remains empty as shown in the diagram from the Logic+ Combi manual below.

Thank you so much!

This is why I started this post with: "Never changed, just kept switching boilers". Now I can see it shouldn't work but it does. I only added this, just in case I'm not aware of something, or there is a valid reason why was it set up like this.

So I believe that either there is something you are not telling us, or if not, this is a wind up.

No wind up this is why I posted photos, I just need help how to wire this.

If it is a Dual Channel Hive, the N & L are straightforward. And then the switched live terminal from the boiler (that has one of the black wires in) goes to Hive terminal 4. They are the only 3 wires needed. No links required. The other room stat terminal remains empty as shown in the diagram from the Logic+ Combi manual below.

- Ok, so L & N are ok.
- I have removed the link
- Cable from terminal 4 goes instead of one black wire
- what about the second black wire? Which terminal should it go to? 2?

This might help to explain the difference between Dual Channel Hive and Single Channel Hive terminals

Thanks, but all I need to know is which terminal (1,2,3,4) needs to be connected to the room stat in order to control the heating. I am not planning to control the water temp. Based on the diagram posted above it looks like terminal 4 should go to one of the room stat connections, and terminal 2 should go to L yes? but then what should be connected to the second room stat in/out? Thats the piece I'm missing
